Josh didn't tell one important part of his story - so I will (I'm his Dad)
After seeing the success he was having, watching many of the videos, reading some books, and being convinced of the science; and in no small part being motivated by the death of my sister from diabetes about a year a go - Josh's mother and I have both taken up the whole foods, plant based diet, starting last Thanksgiving. At age 66, I like to think that I'm not too old to try something new.
I think both mom and I can credit Josh with saving our health from inevitable decline and possibly premature death. We are both very happy with what has happened and are totally convinced we will never go back to the way we ate before. She has lost more than 50 pounds (to be fair, some of that was on a different diet), and I've lost 30 pounds. Still a way to go, but I'm seeing the possibility of getting to normal weight for the first time in 30 years. Just as important, our blood sugars are both very normal and our cholesterol numbers are both in the 110 range - a really good start.
I think Josh's committment to this lifestyle has probably improved our quality of life and longevity by a large factor. We are now working on convincing the rest of the family to go down this road with us. Wish us luck! Thanks, Josh!
